The John Deere RTK activation is required to achieve the highest level of accuracy and repeatability at +/- 2.5 cm (1 in.)*.
Producers can select between two real-time kinematic (RTK) solutions: John Deere Radio RTK, which transmits the RTK corrections by radio, or John Deere Mobile RTK, which transmits the RTK corrections through an existing JDLink™ cellular network.
Each solution requires the John Deere RTK activation. Both methods of RTK corrections offer fast start-up times with a StarFire™ receiver, which will achieve 100 percent accuracy in less than 1 minute.
* The John Deere Mobile RTK signal pass-to-pass accuracy of +/- 2.5 cm (1 in.) is defined at a baseline distance of 20 km . Performance will vary based on network geometry. Pass-to-pass accuracy specifications assume a 15 minute time period, 95 percent confidence interval, clear view of the sky, and no signal interference.
More than 200 John Deere dealers across the United States and Canada have set up a large, robust RTK network. This is beneficial for several reasons:
Contact a local John Deere dealer to inquire about RTK network coverage.
With many real-time kinematic (RTK) solutions, automatic guidance simply stops working if trees or rolling terrain interfere with the line of sight between the base station and the machine or in areas with limited cellular coverage. That is not the case when using RTK with John Deere, thanks to RTK Extend capability.
RTK Extend allows AutoTrac to keep functioning for up to:
The StarFire receiver automatically transitions to RTK Extend when line of sight to the base station is lost or the cellular coverage is limited.
RTK and StarFire 3000 Receiver
When using the StarFire 3000 Receiver, the machine receiver automatically transitions to the SF2 signal when RTK Extend expires. This allows operators to take advantage of +/- 5 cm (2 in.) pass-to-pass accuracy along tree lines, hilly terrain, or in areas with limited cellular coverage. The availability of SF2 provides RTK users with the best available accuracy by lessening the impact of any given field condition.
The machine receiver will transition from RTK to RTK Extend, to SF2, and back to RTK without disengaging AutoTrac.
Broaden RTK availability with repeaters
RTK repeaters are radios that can be used to improve base station signal coverage around obstacles, such as trees or rolling terrain. The purpose of the RTK repeater is to receive the correction signal coming from the base station and then transmit that correction signal.
More than one repeater can be used with one base station, but the repeater cannot receive signal from each other in a daisy-chain configuration. In order to operate, a repeater must be connected to a 12-V power source.
A repeater is the same as the radio that is on a machine or base station receiver.
A repeater consists of the following:
